From the Publisher
Learn to speak the language of APIs
Starting with the fundamentals, this book will give you a primer on all the terminology you need to understand and talk about APIs with confidence. Beyond the language you need to speak about APIs, you’ll learn about the languages you need to speak to them, with coverage on API Specification Languages, including RAML, API Blueprint, and OpenAPI (previously Swagger).
You’ll learn what APIs really are, their origin, and all the different types of API calls that can be made using them. You’ll be introduced to Postman, learn how to set it up, and grasp the basics in a hands-on way by setting up your first API inside it. You’ll explore the different types of APIs you can create and work with, learn how to interact with them, how to break them, and then how to figure out what went wrong.
Speed up your workflow with automation
Learn the art of automating the right way. Not all testing is the same, and not everything is improved by automation. Let expert author Dave Westerveld use his many years of experience to guide you in picking which tests to automate and which ones will be better off left to a human.
When you’re ready, you’ll move on to learn the different types of tests you can automate, how to organize and structure them for the most useful business results, and how to make sure the automated tests you make are repeatable and maintainable.
Use data-driven testing and workflow testing to deliver outputs users need
Data-driven testing enables you to take a whole new approach to organizing your test automation that will let you build one test and use it to check many outcomes. This powerful technique will help you to learn a lot about the API you’re testing with relatively limited input and in a short space of time.
Workflow testing lets you analyze real-world business problems that often require users to call multiple endpoints, sometimes in succession. You’ll learn how to set up and use both linear and business workflows, practice using them in Postman, and even look at considerations for what to do when you need to design workflow tests that extend beyond Postman.
Brand-new for this edition—security and performance testing
Explore two brand-new chapters that will expand your horizons in the API testing space—API Security Testing and Performance Testing an API.
The first new chapter will introduce you to key security testing concepts; such as, what approaches you might take for different types of security testing, the OWASP API Security Project, and using fuzzing to find hidden vulnerabilities.
The second one gets you started with performance testing to ensure your APIs will work when they’re needed, even under unexpectedly high loads. You’ll cover the types of performance tests you can do, how to decide which ones to use and when, and then get your hands dirty by running your own performance tests in Postman.

Become More Efficient and Productive Testing and Developing APIs
These days, APIs are ubiquitous, nevertheless, it is still difficult to discover their usage, capabilities and test them without a specialized tool.For many in the IT industry, it is hard to think of a more proliferated tool for the APIs testing and exploration than Postman.So why not to leverage it to its full potential and rip maximum benefits?This book is focused exactly on this.For myself, a daily user of Postman, many areas of remained obscure and hardly visited.This book broke into these areas guiding gently and affirmatively toward various useful goals of an IT practitioner (be it a developer or QA analyst).I liked how the author sets the stage in the book so it becomes easy for even a novice to approach APIs.The most useful parts of this book for me were on creating mocks, test automation and integration with CI.What remained uncovered, but I wished was fleshed out are the paid parts as working in teams (e.g. collaboration), cloud integration, flows, etc.Still a solid five.Fasten your belt and become more efficient and productive testing and developing APIs!

Great Resource for Postman
I’ve been using Postman for sometime and wanted to learn more about how it works. This book was a fantastic resource and I’ve since upped my game in using Postman thanks to this book!

Ho usato Postman per il mio lavoro per tanto tempo, ma grazie a questo libro ho capito che lo sfruttavo solo al 10%!Che siano state sviluppate da noi, o che invece si stia debuggando quelle sviluppate da terzi, testare le API è di fondamentale importanza.La cosa che mi ha piacevolmente stupito di questo libro è che condensa, in relativamente poche pagine, una quantità enorme di informazioni essenziali tali da poter sfruttare al 100% un software potente (e gratuito) come Postman.Il libro infatti, ha un taglio molto pratico, con la teoria essenziale nelle prime pagine e poi subito con le mani in pasta nel software.Attenzione però: questo libro non è un “semplice” manuale d’uso di Postman.Al contrario, l’autore è partito dagli scenari che normalmente si affrontano durante il lavoro quotidiano per presentare gli argomenti illustrati.Ed è questa la cosa che mi è piaciuta di più: da programmatore, mi sono subito ritrovato negli scenari illustrati nel libro, ho trovato immediatamente la soluzione agli stessi problemi o interrogativi che mi ponevo durante lo sviluppo delle mie API.Gli argomenti toccati sono tanti e vanno da quelli più semplici come le specifiche OpenAPI e la documentazione a quelli più complessi e avanzati come i mock server, la security e le performance.â Consiglio vivamente questo libro, ai tester ovviamente, ma anche agli sviluppatori: le nozioni apprese diventano utilissime sia in fase di sviluppo delle proprie API che in fase di test (e, a dire il vero, torna molto utile anche se si vuole studiare le API di terze parti…ð)
